BEARING.

To all whom it may concern:

Be it known that I, SIDNEY J. SYDNEL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Bearings, of which the following isa specification.

My invention relates t'o step or thrust bearings, and the object of my invention isto provide bearings for the .shafting of heavy machinery, notably turbine generators, which shall be as nearly frictionless as possible and self-balancing, the means for this latter purpose being the use of a liquid cushv ion, which may be oil or other suitable body. n

These and other features of my invention are more. fully described hereinafter, reference being had to the accompanying drawings, in which,- f

Figurel l, is a View of one form of bearingl made in accordance with my invention, onehalf of which is shown in section on the line 3-3, Fig. 2;v Fig. 2, is a plan view of the structure, partly in section on the line 2-2, Fig. 1; Fig. 3, is an enlarged sectional view illustrating a detail `of my invention; and Fig. 4:, is a view illustrating a detail 'of the structure shown in Fig. 1.

The'shaft, in this instance vertically disposed, is indicated at 1, and is .reduced at the points 2 for the engagement of a sleeve or collar 3 having annular grooves 3a to fit the ribs 2a of the shaft. This sleeve or collar is in two sections, as clearly shown in lthe plan View, so as to be readily applied to the shaft; the sections being suitably secured by bolts, screws or other means indicated at 4;. Surrounding the shaft and Lthe collar before referred to, is a supporting'or base member made lin two parts, indicated at 5 and-6; the part 6 resting upon a suitable base 7 while the part 5 rests upon the part 6. Interiorly, the part 5 is of such contour as to accommodate the lower. portion of the collar or sleeve 3. The collar in this present arrangement has projecting annular portions 10 which, of course, rotate with the shaft and rest upon roller bearings which, in the present'instance are composed of disk plateslland 12, between whicha series of small rollers 13 are arranged concentrically and confined in place by a suitable collar 14; so as to overcome their` tendency to leave the bearing plates. 'These roller bearings,

vof which there are two in the present instance, rest upon disks 15; the upper one of l f Specification of Letters Patent.

which'i's mounted upon the top of'the member 5 of the supporting or base structure, and these disks 15 are supported by the fluid body. 4The means for .accomplishing this are shown in detail in Fig. l3, and in each instance consist of av ring 16 substantiallyy U-shaped in cross section, let into the top This ring is recessed adjacent the inner and outer walls as shown at 17, and fixed in these vrecesses are bands of leather 18 or other suitable material which ring 2O is then placedy between the bands of leather;` suclr cover ring having recessed edges 21,' and the upper edges ofthe leather bands are turned so as to engage these recessed portions-in the manner shown in Fig. 3. Closing the space betweenl this cover ring 2O and the top of the U-shaped ring, is a ring 22, having slightly beveled sides so as to be incapableof binding mits seat, and this cover ring20 andthe upper one receiving the leather bands are secured together by screws 23 in the manner shown. The structure just described is duplicated in the member 6, for which'further description is thought unnecessary. To supply oil to these parts of the structure, the portions 5 and ,6 are bored as shown at 25, in line with apertures 26 in the bottom of the U-shaped lrings. 16, and connecting these bores is a may be held in place by .rings 19. A cover thereby. This arrangement for forcing the oil or other liquid makes possible the use pf a plurality of bearings by dividing the -oad.

operation, and insures the proper balancing of the shaft.

I claim: v l. The combination of a vertically disposed shaft having annular grooves, a plurality of supporting ianges secured to said shaft adjacent its grooves, a plurality of anti-friction .f bearings upon which said which the latter-rest,- said base being pro-V vided with circular recesses to receive said rings, exible material connected to' said rings and the base and providing-iuid tight .chambers having iexible walls beneath said rings, and means for directing fluid under pressure to said chambers to act upon said 2. In a thrust bearing, the combination of a shaft, a collar thereon provided with a thrust face, a. thrust abutment, an annular pressureactuated diaphragm surrounding the shaft and mounted on said abutment;

loadfoarrying means supported by the diaphragm, and rollers between said means and said collar.

3. In a thrust bearing, the combination' of a vertical shaft, a collar thereon provided i with a thrust' face, a relatively fixed thrust abutment, an annular pressure-actuated flexibly mounted diaphragm `surrounding the shaftand supported by the thrust abutment and givingsupport to the thrust face, a plurality of disk plates interposed between l for,

the diaphragm and said thrust face, and rollers mounted between a pair of said plates.

4. In a thrust bearing, the combination of a shaft, a collar thereon provided witha thrust face, a relatively Vfixed thrust abutment, and an annular pressure actuated flexibly mounted diaphragm. surrounding the shaft and supported by the thrust abutment and giving support to the thrust face, and rollers `interposed between said dia phra-gm and said collar.

5. In a thrust bearing, the combination of a shaft, `a collar thereon provided with a thrust face, a thrust abutment, an annular pressure actuated diaphragm surrounding the shaft and supported by ythe thrust'abutment, a plurality ofannular plates mounted onsaid diaphragm, one of which is a bearing plate, and rolling elements interposed between said bearing plate and the thrust face of the collar.

'6. In a bearing, the combination of a plurality of collars having load sustaining faces with-a plurality of fixed abutments therepressure actuated supporting diaphragms between said faces and abutments, a plurality of load carrying means supportedby said diaphragms, rollers between "said means and the collars, and means for g the pressure to` supplying and controllin saidY supporting diaphragms.`
